Which code denotes the normal relay used as a substitute for a lever in the normal position?

Explanation:
When a relay takes over the function of a lever in its normal (rest) position, maintenance codes are used to convey that exact setup. The code in question explicitly describes a normal relay substituting for a lever while the lever would be in its normal position. The N indicates normal/rest, the L stands for lever, and the P signals that the relay is acting as the substitute in that position. So this code communicates that the circuit state is being maintained by a relay in place of the lever, in the lever’s normal position. That direct match is why it’s the best description for this situation.
